What is SynoLocker:
Threat Classification: Ransomware
SynoLocker is the newest version of Crypto Ransomware infections. Similar to Cryptorbit, HowDecrypt, CryptoLocker, CryptoDefense and CryptoWall. SynoLocker will target computers running Windows operating systems, but the most striking difference between this one and it predecessors is that it can encrypt files on your NAS (Network Attached Stoarage) device, and more specifically the one of the firm Synology (NAS and DiskStations). It was released and detected in August. SynoLocker is almost identical to its predecessors. There are a few minor changes like the name, the files it drops and modified instructions with a new picture. Unfortunately, as of now, there is no chance of decrypting the files encrypted by SynoLocker.
SynoLocker will fully encrypt your data compared with its predecessors. The infection might come from various sources – infected files from various P2P networks, torrents or other file sharing applications, bogus flash player, Silverlight updates or fake video software for viewing online content, email attachments etc. When activated, SynoLocker encrypts certain types of files stored on your local and mounted network drives using RSA-2048 bit public-key cryptography, with the private key stored only on the malware’s control servers. SynoLocker leaves access database files untouched, but does encrypt .doc, .xls, and .bmp, .txt, images and videos.
The SynoLocker malware files are stored on the Synology device in the /etc/synolocker folder. The main decrypter program is located at/etc/synolock/synolock, the private decryption key is located at /etc/synolock/RSA_PUBLIC_KEY, and the public key is found in/etc/synolock/RSA_PRIVATE_KEY
The malware then displays a ransom message which offers to decrypt the data for 0.6 Bitcoins, which is about #350 at the moment. If the payment is not made by the stated deadline, SynoLocker threatens to delete the private key. In order to pay the ransom the users are sent to a specific webpage where they can enter their personal code and access a payment page. The page can be accessed through Tor client:
or through normal browser:
The payment should be made through Bitcoins – untraceable payment method.
Once the infection is executed on your computer, it will inject itself deep into the system by modifying the registry in order to start with Windows on every boot. Then it will start encrypting files. This is a newborn virus and is very hard to detect. However, the infection will manifest itself after the encryption process has been completed.
SynoLocker will not only encrypt your files and lock your computer. It will also collect information that might be used to compromise you. The ransomware may steal other relevant information as your personal details, and send it over to the creators. That is the reason why this malware infection should not be left unattended, and it needs to be terminated immediately, as it is a serious threat to your online security.
*Please note that, unfortunately, as of now there is no method of decrypting the files encrypted by SynoLocker. The infection will also delete all your Shadow Volume Copies. The only way to restore your files is by using a backup copy.

1. Remove SynoLocker by restoring your system to a previous state.
1. Reboot your computer into Safe Mode with Command Prompt. To do this, turn your computer off and then back on and immediately when you see anything on the screen, start tapping the F8 key on your keyboard.
***For Windows 8:
If you are using Windows 8, you need to hold the Shift button and tap the F8 key repeatedly, this should boot you into the new advanced “recovery mode”, where you can choose the advanced repair options to show up. On the next screen, you will need to click on the Troubleshoot option, then select Advanced Options and select Windows Startup Settings. Click on the Restart button, and you should now be able to see the Advanced Boot Options screen.
2. Using the arrow keys on your keyboard, select the option “Safe Mode with Command Prompt” and press Enter on your keyboard.
3. When the command prompt loads up, type:
Windows XP: C:\windows\system32\restore\rstrui.exe and press Enter
Windows Vista/7/8: C:\windows\system32\rstrui.exe and press Enter
4. System Restore should initialize, and you will be displayed a list of restore points. Try using a restore point created just before the date and time before the Your-computer-has-been-locked virus has infected your computer.
When System Restore has completed its task, start your computer in Windows normal mode, you would need to perform a scan with anti-spyware software as the infection might still be on the system.
*Please note that your Synologic NAS or DiskStation files might remain encrypted, depending ot wheter your system restore has been set to recover system settings only or your entire system.
*Please note that your files may remain encrypted, depending on whether your system restore has been set to recover system settings only or system settings and previous version of files.
